U.S. President Donald Trump's India tariffs have shown Moscow's allies that he will follow through with his threat to impose secondary tariffs on countries that purchase Russian oil, though doubts remain about the practicalities of implementing them,

President Donald Trump said he would impose a tariff of at least 25% on India’s exports to the US starting Friday, though later added that the two sides were still in talks.

Earlier on Wednesday, Trump announced a 25% tariff rate on Indian goods, along with an unspecified “penalty” for its continued trade relationship with Russia.
